Hello Ed!
That is a bummer! It looks like this company has been sued "practically out of business" so to speak because, I did a search on a variety of search engines, and all I found were alot of .pdf files regarding lawsuits against them for a variety of reasons, and some other pages which were from out of this country that really did'nt offer any info regarding your situation... No wonder they're of no help!!!
Most of the equipment repair sites offer repairs to only major brands so, they were of no help!!!
However, I took the liberty to do a search for "circuit board repairs", and found a couple of possibilities:
(1) Precision Electronic Services Inc.

There are probably more companies out there but, this is all I found that could help your situation...
I do'nt mean to offend you but, have you taken a closer look at the board itself, not including the components?
The reason I ask is that you may have a problem with the board itself and not any of the components attached to the board...
a couple of other questions, if you do'nt mind: How did you diagnose the problem being found in this circuit board? Was it because, the machine had a schematic inside, on one of the sheet metal enclosures or was the schematic found in the machine's instruction manual?
When you contacted the manufacturer, (NuTecsys) did they tell you who manufactured the circuit board? Is the Mfg.& model number printed on the board?
This could really help because, I have repaired alot of out of warranty equipment in some "rare" brands of welding and cutting equipment before, and usually these parts can be obtained rather inexpensively when you compare the cost of replacing the equipment over performing the repairs.
However, if you need this plasma cutter, and are turning away jobs because, of it not working then, I STRONGLY suggest that you buy a new replacement!!! This time do'nt mess around with anything other than the major brands that are being serviced at your welding/gas suppliers in your area...
(Thermal Arc, Hypertherm, ESAB, Lincoln, Miller, etc.)
I hope this info helps, and I hope I did'nt offend you...I apologize if I did!
Respectfully,
SSBN727 Run Silent... Run Deep!!!
